To all 'w/imri it mo i comfem ticks in the Work oi sin ing oil Wells; the

object 01E the invention being;- the piodiietioii oi :1 cult wheel, which shall have free role.- tiou on its fixed sustaining shutt. whereby binding of the same is overcome in e: :ie of the shalt getting out o'l? true oliueiiuriit with beoiii'io' by ilj'coeoii of on. l'lll lltl'l l sagging or settling oil. the trnine timbers supporting the szuue.

To comprehend. the invention, reference should be had to the occoio itieyice: difnu ine's, whereiu-- l igure 1 is l perspective View of the intproved Wheel held. to the jlirniue pieees of on oil derrick.

lo. the (ii-airings. the iuuu'ieriil 1 is used to desiguote or metallic cylindrical shell on which the cult liiuc :able is Wound, and. 2 21 sustaining shaft for thceoid shell. This shell. is termed on its iuuer si'irjlthee ivith a. series of radial disposed projections or ribs 1-}. which bear onto the sort; .:e oi? the sustaining; sluivlt and serve t slreuittheii the cylih dricol shell to revent the crushing ljl'llzl'GOil under the compression striiiils to which the some is subjected by the Windiz'ig' oil. it cable thereon. thereby emihlihgj; it much lighter shell to be used tlmu otherwise could he si'iccessively employed.

These bolts embracing) the ends (it thi sueloiiiine' she'l t secure the some. secuii'ely within the soot in the bearing: iihites or supports 12 and ho d the shailit :ieniust rotutioi'i.

'jlhc drum or shell 1 being loosely si'lp'ported on the sustniir 1 shaft and tlfree to rotate thereon without trensmittitu its 11loveu'ieut ot' rotetioii to the said shril'ft there is no teiideuey tor the rotatable drum or shell. to bind iii any manner in case of the supporting iii-lime ii 'uieflite sagging; due to the E-lll'tllll-a placed thereon, the shell or drum being; thus held in elinement with. the fixed shaft 2 under all working conditions, and by reason of its free rotation on the said shattthere is no tendency of the same to bind, although its sustaining shaft may get out of true longitudinal alinement.

On the outer end of the hub at is loosely mounted the disk or circumtere tial flange 16 therefor, and between the same and the inner circiunlerential flange 5 ol such hub the disk web of the drive member is securely held by means of the transversely disposed connecting bolts P. This web is composed of a plurality of layers a, Z), 0, consisting each of segmental wooden pieces, which are built up to form a solid web, the outermost .lcf-TQT a of the series ot'layers being; extended a slight distance beyond the periphery of the layers 2) and c. The periphery of the layers 7) and 0 are embraced or encircled by a metallic rim 16, which rim is pr vided. with and carries a sprocket-ring 17, which constitutes a drive ring for the calf wheel. To the web thus i rnied is united a built up brake surface for the drive member of the calf wheel, the same consisting of a series of segmental pieces 17 which are placed together and united to the web or the drive disk by means of the transverse bolts 18, which extend through the segmental pieces 17, and the metallic rim 16. The brake surface thus formed is provided with a metallic brake band or rim 18', which is engaged by any suitable form of brake mechanism, not shown, and onto said band or rim falls the frictional wear. 7

The built up drive disk driven by means of a sprocket ch not shown, working over the sprocket ring 17, which chain is usually driven from a sprocket pinion on a crank shatt within the frame of the oil derrick. However, rotation may be imparted to the drive disk by any suit-able form of power mechanism.

By the use of the described drive dis;

applied to a calf wheel, the driving power more ellectually applied to the said wheel tie employment of brake surface independent of the drive disk, besides a compact form of a drive and brake disk is providcd for the calf wheel.

Having thus described the invention what is claimed as new and desired to be protected by letters Pate t is In a calf wheel cil derricks, the com bination with a fixed sustaining shaft, a shell loosely neunted thereon for free rotalion, end bearing hubs loose on said shaft and united to the ends of said rotatable shell, end collars adjustable on the sustaining shaft for preventing longitudinal movement of the hubs and she l relative to said shaft, annular flanges projecting from said hubs, a drive disk secured to said last mentioned flange, said drive disk being composed of a plurality of segments arranged in layers, each layer being arranged transversely to an adjac a layer to form a solid mass, a. drive rf encircling the periphery of said drive disk, an annular brake member constructed of a plurality of annular segments and of a diameter greater than said drive disk, a metallic brakeband surroundin said brake member, and means for uniting said brake member to said drive member and for retaining said drive ring in position on said disk.

in testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
